摘要

为了研究TiO

禁带宽度和光吸收系数对其光催化性能的影响

使用Materials Studio的Dmol3和CASTEP模块分别对Ag

、Fe

、Pt

的禁带宽度变窄、吸收波长红移

相同光照条件下光吸收系数增加

影响了TiO

TiO

的禁带宽度为1.09 eV时光催化性能最好

TiO

的光吸收系数越大

光催化性能越好。

Abstract

The effects of band structure and optical properties of TiO

doped Ag

ions were analyzed by using Materials Studio. The molecular simulation shows that metallic ion doping can make the forbidden bandwidth of TiO

narrow

the absorption wavelength of TiO

red-shift

and the optical absorption coefficient increase in the same light condition. The changes affect the photocatalytic ability of TiO

. Under 254 nm UV light

TiO

shows the best photocatalytic ability when the forbidden bandwidth is 1.09 eV

and the higher optical absorption coefficient.
